I need help with my 780 Bertone. I just did a complete overhaul on the engine (4 cylinder Turbo). New rings, sensors, gaskets, seals, etc. After assembling the engine it started fine with no noises or anything else. After running it fow a while it developed a very, and I mean very loud knocking sound like if the pistons want to come out of the block. The car runs fine otherwise, except this noise. I remembered checking everything before reassembly but now I'm not sure. I also noticed the other day that while checking the timing, it was off quite a bit, but I'm not sure how to set up the timing on these engines. This car otherwise is in excellent shape. Also noticed the other day that the oil ligth was coming on. Any help out there will be greatly appreciated.

thanks,

Luis
